AquAdvantage Salmon FDA Approval Process

The AquAdvantage Salmon FDA Approval Process followed the regulations for New Animal Drugs under the Federal Food Drug and Cosmetic Act (FFDCA) and the U.S. FDA's guidance on regulation of genetically engineered animals. If approved, the AquAdvantage salmon will be the first genetically engineered (GE) animal to directly enter the U.S. food supply. It is also the first GE animal to undergo the FDA's regulatory process for approving GE animals.

In early September 2010, the FDA issued a preliminary finding that the AquAdvantage salmon is safe to humans and the environment. A few weeks later, the FDA held two public meetings on the issue September 19-21, 2010. The first, a meeting of the FDA's Veterinary Medicine Advisory Committee (VMAC) took place September 19-20, addressing the scientific issues associated with the approval of GE salmon. The second, a public hearing in which the FDA presented the legal principles for food labeling and offered the public an opportunity to comment, took place on September 21, 2010. Prior to the meetings, the FDA released a number of documents, including a briefing packet for the VMAC meeting describing the science used to determine the GE salmon's safety.

The regulatory and approval process for the AquAdvantage salmon has been criticized for being insufficiently transparent, for failing to provide enough time for public comment, for failing to appoint experts with appropriate and sufficient expertise to the VMAC committee, and for accepting "sloppy" and "misleading" science as the basis for the FDA's initial decision that the GE salmon is safe.

About AquAdvantage Salmon
AquAdvantage salmon is a genetically engineered (GE) salmon produced by AquaBounty Technologies. AquAdvantage salmon grow to market size in 16 to 18 months instead of the usual 30 required for Atlantic salmon. AquAdvantage salmon are identified as "Triploid hemizygous, all-female Atlantic salmon (Salmo salar) bearing a single copy of the α-form of the opAFP-GHc2 rDNA construct at the α-locus in the EO-1α lineage." In other words, the salmon will each have three complete sets of chromosomes instead of two, and all of the fish will be females. For more information, see the article on the AquAdvantage salmon.

New Animal Drug Application (NADA)
According to FFDCA's New Animal Drug Provisions, AquaBounty Technologies, the maker of the AquAdvantage salmon, had to submit a New Animal Drug Application (NADA), including an environmental assessment or a claim of categorical exemption. Following an application, the FDA has 180 days to either approve the New Animal Drug or offer the applicant a hearing.

Safety Testing of AquAdvantage Salmon
The FDA released its assessment of AquaBounty's safety testing of AquAdvantage salmon in a 180 page document in September 2010. The science used to justify the GE salmon's safety was quite sloppy, as noted by the FDA in several cases in its analysis and as stated in comments submitted by Consumers' Union. For more information, see the article on Concerns About Science Justifying the Safety of AquAdvantage Salmon.

Environmental Assessment
Prior to FDA approval, the AquAdvantage was required to undergo an Environmental Assessment (EA). One of the main concerns addressed in the assessment is the potential for the GE salmon to escape into the wild, particularly if it would be able to survive there and compete with wild populations and/or interbreed with wild populations. For more information, see the article on the AquAdvantage Salmon Environmental Assessment.

VMAC Meeting, September 19-20, 2010
The Veterinary Medicine Advisory Council met to discuss the approval of the AquAdvantage salmon on September 19-20, 2010.

Public Meeting on Labeling
The FDA held a public meeting on labeling issues related to the AquAdvantage salmon on September 21, 2010.

Concerns With the Approval Process
In comments submitted to the FDA, Consumers' Union noted that the FDA was violating the law for approving New Animal Drugs, as all of the safety data about the GE salmon came from salmon raised in Prince Edward Island (PEI) and the approval, if given, would be for salmon raised in Panama. Consumers' Union added that the FDA itself admitted that there would likely be phenotypic differences in fish raised in Panama compared to those raised in Prince Edward Island: 'A fundamental problem with all the phenotypic characterization data, and indeed all the nutritional and food safety assessment data, is that they all come from GE Salmon raised in the PEI facility, not at the facility in Panama. FDA admits that the culture/husbandry conditions at the facility in Panama will likely differ significantly from the conditions at the PEI facility with unknown effect on the GE salmon’s phenotype but then concludes that it has no concerns with the different culture conditions: "the culture (e.g., water temperature, pH, alkalinity, etc.) were likely to be significantly different from the facility at PEI as a result of differences in, among others, water surface, facility design, and environmental factors due to geographic location. . . .  the effect of the difference between the PEI and Panama facilities, especially temperature, on the resulting AquAdvantage phenotype is unknown." ... We do not understand how FDA can conclude, in the absence of any data on the phenotype of GE salmon raised at the Panama facility, that there are no animal health concerns with GE salmon raised at the Panama facility... This should be unacceptable for a GE animal approval, as it appears to violate the NAD regulations.'

Consumers' Union continues, explaining: "FDA is regulating the GE salmon as a New Animal Drug, with the NAD being the genetic (e.g. rDNA) construct itself. Thus, the husbandry and rearing conditions of GE fish into which the genetic construct has been inserted would constitute the production process. Under the NAD provisions of the Federal Food Drug and Cosmetics Act (FFDCA), a NAD is granted for a specific production process; if a company changes the production process for a NAD, the company must submit data to the FDA to show that such a change does not have an effect on the safety or efficacy of the NAD, i.e. the FDA does not assume that drugs made with different production processes are equivalent and requires data to show they are equivalent. Since the husbandry/rearing conditions differ between Panama and PEI—the former being in the tropics, the latter in the temperate zone—this means that the production process (e.g. husbandry/rearing conditions) differs as well, and FDA should require Aqua Bounty to submit data showing that it does not impact the safety of the NAD. FDA should insist, for example, that the rearing conditions in Panama do not increase the levels or potency of allergenic proteins in the salmon."

In a separate letter, one sent to FDA Commissioner Margaret Hamburg and Deputy Commissioner Joshua Sharfstein, Consumers' Union also notes that the public comment period is exceptionally short - 14 days as opposed to the usual 60 or 90 days given - and that the members of the Veterinary Medicine Advisory Committee are not qualified or unbiased in their expertise to make the approval decision.
